Question

Jatin added a crystal of copper sulphate (CuSO4) in a beaker filled with water and left it to settle at the bottom. After sometime he observed that the blue colour appears just above the solid crystal and with the passage of time whole water in beaker turns blue.

Amoeba acquires its food through a process termed as:

Define osmosis and explain how it differs from diffusion, providing different examples to illustrate each process.

Assertion (A): The rate of mixing of copper sulphate or potassium permanganate crystals is faster in hot water than in cold water. Reason (R): The increased temperature of water decreases the kinetic energy of the water molecules, leading to faster movement and quicker dissolution of the crystals.
